Application filed May 4,

My invention relates to separators for use in extracting or separating moisture. and solids from steam, air and gas lines and the object of the invention is to provide a combined centrifugal separator and drip pocket for use in horizontal lines or pipes and which shall be highly efiicient. A further object of the invention is to provide a device of the kind above outlined, which shall be specially adapted to take care of and dispose of accumulations and slugs of water or other foreign substances in advance of the final centrifugal cleanipg operation or action. 9 1- y The structure embodying the invention and the manner in which the foregoing objects are attained will be clearly understood on reference to the drawings that form part of this specification; and in which Fig. 1 is a vertical longitudinal section of a separator embodying this invention; Fig. 2 is-a sectional vievv on the line 2-2 of Fig. 1-; Fig. 3 is a cross section on the line 3-3 of Fig. 1, on a reduced scale. Fig. 4 is a side view'of the separator; and Fig.5 illustrates a modified form of the separator head whereby successive centrifugal actions are accomplished.

Generally, the separator embodying this invention should be made in two parts, namely, anv upper part or head and a drip pocket hanging therefrom. The head is mainly circular in cross section and is hollow. At one end it contains an inlet opening 2 and at the other end an outlet opening 3. Between these openings is a transverse ring or partition 4. which contains a third central opening, marked 51., Preferably also, the zputlet 3 is distinguished by an annular 1i ilt will be seen that the head is divided into two generally circular cavities 6 and 7, of greater diameter than the openings 2, 3 and 5. The cavity 6 has a drain 6 and the cavity 7 a drain '7', that is, each has an openin in its bottom for the discharge of the su stances that are collected centrifugally, as about to be described. Beneath the opening 6 and 7 isthe drain pocket 8 having a valved drain 8 at its lower end.

' Directly at the opening 2 is a; device which deflects. or turns the incoming stream of steam, gas, or air, and sets it into rotation in the cavity 6, and thereby most of the N 1925. Serial No.,27,860.

heavier substances are cent-rifugally separated and caught against the intermediate partition 4. Being in whirling motion the heavier substances are' promptly ejected through the opening or drain 6' and fall Meantime, the

into the drip pocket 8. whirling steam, gas, or air thathas been completely or partly freed from its burden,

whirls-through the opening 5 and expanding suddenly into the chamber 7 centrifugally deposits the remainder of its burden therein. and thence into the pocket 8. The purified fluid leaves the chamber 7 through the central outlet 3.

A fluid whirling "device of great d ependability and. which offers little resistance to the passage of the fluid is shown at the inlet end of the described head. This whirling device is itself stationary, being composed of a plurality of circumferentially spaced blades 9, all having the same direction and forming the several tangential inlet tuyeres 10. Preferably these blades are integral with the body of the head. The. part 11 represents either the end of the pipe which supplies the fluid, or a separate casing which forms a continuation thereof. Being larger than the. ring of blades 9 it presents an annular cavity 12 about that ring. That cavity has a cross section equaling and preferably exceeding the cross sectlon of the opening 3. Incidentally, as an end is required for the ring of blades, that end 13 may be formed in the member 11. It prevents the direct passage of the fluid. Therefore, the fluid enters from the cavity 12 and passes tangentially into the rin with the result that it .is set into rapi whirling motion therein. This whirling motion results in the first or initial centrifugal separation of the heavier from the lighter substances so that as the whirling stream enters the'cavity 6' the heavier substances are found upon the outside of the whirling stream ready for collection in that expanded race.

The invention is not limited to either of the precise "constructions above described, and comprehends such structures as that illustrated in Fig. 5. The latter will be understood from the foregoing description of the head. i It is distinguished by an added centrifugal separating cavity 14 and drain 14' and preferably the central openings 15, 16 and 3" diminish in size toward the LOO latter, this last being desirable as a means of avoig m excessive drop of premre.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

l. A separator head having a horizontal axis, in combination with a drip pocket depending from said head, said head having an inlet at one end and an outlet at the other, an intermediate partition having an opening that is coaxial with said inlet and outlet and which divides the head into separate centrifugal collection cavities, each said cavity having a drain communicating one end and an outlet at the otherand containing a transverse. partition having an opening of a diameter at least equaling that of said outlet, a drain at the bottom of said partition, and a circumferential series of fluid whirling blades projecting axially from the inlet end of said head.

In testimony whereof I have hereunto set my hand this 30th day of April A D. 1925.
